摘要:
2-Vinyloxyethyl isothiocyanate reacts with aromatic diols: catechol, resorcinol, hydroquinone, 2,3-dihydroxynaphthalene, and 2,2-bis(p-hydroxyphenyl)propane, in the presence of 0.25-0.5 wt % of trifluoroacetic acid (55-80 degreesC, 0.5-2 h) to give bis-acetals containing isothiocyanato groups in quantitative yield.
